Reading XML with QT

rowancompsciguy · 06-29-2008, 04:29 PM

I'm trying to write a function using QT to read in data from the Yahoo! weather feed so that I can parse it and put the data in a widget. I can't seem to get the data to come over though. Does anyone see anything wrong with my code? It compiles fine. I'm new to QT however and I would really appreciate some pointers.

Code:

char* Plasma_Weather::collectData()
{
   QHttp* http = new QHttp();
   QBuffer* buffer = new QBuffer();
   QUrl url("http://weather.yahooapis.com/forecastrss?p=08002");

   buffer->open(QBuffer::ReadWrite);

   http->setHost(url.host());
   http->get(url.path(), buffer);
   http->closeConnection();

   QByteArray array = buffer->readAll();

   delete http;
   delete buffer;

   return array.data();
}

You might want to change the title to something like "downloading from URL with QT" - the current title suggests you are trying to parse XML, which doesn't actually appear to be the problem (not until you get the data anyhow).

A good place to start is the QT examples. Here's one with simple downloading in it:
